The Character of Chiaroscuro was created in 1994, and joined FurryMUCK in November of that year. There, he was co-creator of Itza Castle, which was (In Character) based on the ruins of his home in the 10th century and magically incorporated to blend with a Kzin spaceship owned by Jamen-Riit. His middle name of 'Lyle' came from his modern adoptive family of Alice and Larry Lyle.

He is a temporal magician on a subatomic level, able to manipulate particles en masse in order to alter, reverse, and change the flow of time- within certain limits so as not to damage the temporal fabric. He focuses this magic through the use of pebbles, in the way other magicians would use wands or wards.
